LCN 4011-3071DEL Delayed Action Cylinder Assembly, Part For 4010 Series Surface Mounted Door Closer

The LCN 4011-3071DEL Delayed Action Cylinder Assembly is a genuine replacement component engineered for the LCN 4010 Series surface mounted door closers. This cylinder adds a delayed action feature to the closer, giving occupants extra time to pass through the doorway before the door begins its closing cycle. Ideal for high-traffic openings, healthcare facilities, and locations requiring accessibility accommodations, this factory part maintains the reliability and performance LCN is known for. Built to exacting standards, it delivers smooth, consistent hydraulic control and integrates directly with existing 4010 Series hardware to restore or upgrade closer functionality without replacing the entire unit.

Functional Details

The delayed action cylinder allows the door to remain open for a set period before beginning its normal closing sweep, providing additional time for pedestrians, carts, or individuals with mobility needs to clear the opening. The delay is controlled through the cylinder's independent hydraulic valve, separate from the standard sweep and latch adjustments.
